    vfscanf have problem to deal with string in utf-8 format.
    In function:
        externC int
            vfscanf (FILE *fp, const char *fmt0, va_list ap) __THROW {
                    u_char *fmt = (u_char *) fmt0;

        It declared that:
            char ccltab[256];
            char curr_byte;
        When a byte's highest bit(the sign bit) is set, doing the
following conversion:
        it surely will generates an integer that is larger than 256(
Recall, signed bit extension).
        While try to combine it with:
        a fairly bug yields.
